“Smart technology and friendly, knowledgeable, honourable people who genuinely try to provide the right solution for your needs.”

“Their technology is streets ahead, as evidenced by discharge samples and by meeting or exceeding consent parameters.”

“They are 100% professional – personal not corporate.”

“The ability to deliver to tight consents on nitrate and phosphate reduction is critical, we cannot afford failure – PWS provides the complete package, from product to maintenance and operations, and they take away the risk of non-compliance.”

“PWS listens – and they tell you like it is.”

“We have always come back to PWS because others are unable to provide the technology or the service required – and that’s affected gaining the appropriate consents.”

“Service makes them stand out – they are all interested and all on-board with what they’re trying to achieve.”
